Measurement of a helium tune-out frequency: an independent test of quantum electrodynamics
B. M. Henson, J. A. Ross, K. F. Thomas +9
Despite quantum electrodynamics (QED) being one of the most stringently tested theories underpinning modern physics, recent precision atomic spectroscopy measurements have uncovere…
Frequency measurements of transitions from the state to the , , and states in ultracold helium
Jacob A. Ross, Kieran F. Thomas, Bryce M. Henson +4
We perform laser absorption spectroscopy with ultracold He atoms to measure the energy intervals between the level and five levels in the n = 5 manifold. The lase…
The First Measurement of the Tune-Out Wavelength in He*
B. M. Henson
The workhorse of atomic physics, quantum electrodynamics, is one of the best-tested theories in physics. However recent discrepancies have shed doubt on its accuracy for complex at…
Precision Measurement for Metastable Helium Atoms of the 413 nm Tune-Out Wavelength at Which the Atomic Polarizability Vanishes
B. M. Henson, R. I. Khakimov, R. G. Dall +3
We present the first measurement for helium atoms of the tune-out wavelength at which the atomic polarizability vanishes. We utilise a novel, highly sensitive technique for precise…
